Wrong date with $df("dd MMM hh:mma", ai(moonrise, r1d))$

$df("dd MMM hh:mma", ai(moonrise, r1d))$

It's giving the wrong date

It returns today's date (11) instead of yesterday's (10). Works fine for r2d (9) and only seems to effect moonrise

The formula "ai(moonrise, r1d)" will remove one day for current date and then calculate the moonrise which MIGHT be on the day after, if your screenshot is at 9PM and not 9AM then its correct. For example if you ask for $ai(sunrise, r1d)$ at 9PM it will give you a time in the day after as well.

Ahhh yes, I see. Thanks for the clarification
